To all whom t may concern.'

Be it known that I, LESTER M. WALDEN, a citizen of the United States, residing at Chicago, in the county of Cook,in the State of Illinois, have invented certain new and useful Improvements in Perforating-Machlnes for Record-Strips; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this speciiicatlon, and to the viigures and letters of reference marked thereon.

This invention relates to improvements in record strip perforating machines, being particularly designed for use in perforating machines for forming record strips which are subsequently used as the controllers for type casting machines. Recordstrip perforating machines of the character referred tc are now commonly employed in connection with the Lanston monotype? and similar systems for the production or preparation of controllers, such as are employed to govern or control the type making machine in the production of rinting characters. An example of a per orating machine in which the present invention may be employed is illustrated in the patent granted to |Talbot Lanston, No. 654,115, dated July 17, 1900, and inasmuch as the general characteristics of the `machine are now well understood and may be ascertained from the aforesaid patent, a portion only of the machine is illustrated in connection with this application.

Referring to the accompanying drawings,-

Figure 1 is a side elevation of the u per portion of the so-called paper tower o the` perforating machine;

Fig. 2 is afsection in a vertical plane centrally of the portion of the machine illustrated in Fig. 1; and

Fig. 3 is a section showing the nib extractor in elevation. V

Like reference characters throughout the several 'figures indicate the same parts.

The fixed frame of the paper tower is indicated generally in the drawings by the reference numeral 1, and in this frame there is mounted a guide bar 2, in which work a series of punches 3 adapted to move upwardly, each under the control of a finger piece not illustrated herein, but adapted, when depressed, to set in motion mechanismfor advancing one or more of the punches for perforating a strip of. paper which is fed over the guide bar and between said guide bar and a curved vdie located above the guide bar 2 in position to receive a downwardly extending loop of the paper forming the record strip. The paper is fed from a roll such as that indicated at 5 in Fig. 1, around the curved die to a reel 6, the said roll and reel being preferably journaled in supportmg'bearings at the upper end of the frame l. The curved die 4 is preferably of more or less cylindrical form and adapted to receive the punchings or nibs removed from the strip of paper by the operation of the punches. Journaled inthe frame coaxially with the axis of the curved die is a paper feed shaft 7 having upon it pin wheels 8 and 9 adapted to coperate with preliminarily formed'marginal perforations in the record strip, whereby the rotation of the shaft and pin wheels will accurately feed the paper a delinite distance between y cordance with the present invention, how? ever, advantage is taken of the fact that the paper feed shaft passing axially through the hollow die is rotated in the operation of the machine, and a conveyer of the screw type is mounted on said shaft for carrying the nibs or punchings out at one end of the die and through a suitable opening provided for their escape in the frame 1. In the preferred construction the shaft is provided with a sleeve 10 between the pin wheels 8 and 9 and said sleeve is formed with an exterior and relatively deep spiral 11, which will operate to carry the nibs or/punchings transversely of the record strip toward one end of the curvedl die, or toward one of the v with an opening l2, shown in Figz and in dotted lilies in Fig. 2, through which openings the` iiibs or punehings will pass to the outer side of the pin wheel. To prevent the free escape of the punching-s passing through the pn wheel a cylindrical guard 13 is provided on the outer side of the said wheel to bridge the. space between the wheel and the frame l. Said clif'lindrical guard 13 forms a continuation of the chamber formed by the curved die, and from it the nibs or punchings are discharged through an opening 1J: extending diagonally doivn through the frame l, where they may becaught in a suitable receptacle such as that indicated at 15. To insure thel discharge of the nibs or punchings from the chamber formed by the guard 13, a spiral 1G is secured at one 'end to the outer face of thcl pin wheel 9 to operate as a continuation of the spiral 1l on the opposite side of the pin wheel.

IVith this arrangement, the nibs or punchings are discharged as rapidly as they are forced into the curved die; thus, any accumulation lwithin the latter is prevented, and the operator is relieved of the necessity of giving any attention whatever to their removal. Furthermore, the continuous removal of the piinchings as formed prevents any possibility of their getting into the loop of record strip or between the record strip and the die where they are liable to interfere with the roper action of the punches in locating t e controlling apertures, or with the proper action of the pin wheels in feeding the strip for coperation with the punches.

wWhat is claimed is:

l. In a record strip perforating machine, the combination with the frame, die, and series of punches cooperating with the die,

- of a paper strip feeding mechanism for advancing the paper into position for coperation with the punches and die, and a con- .vcyer for the nibs or punchings operating 1n unison with the paper feeding mechanism to carry the said punchings laterally away from the die.

2. In a record strip perforating machine, the combination with the frame, series of punches, and curved hollow die with which the punches coperate, of a paper feed mechanism embodying a shaft journaled coaxially with the curved hollow die, and a spiral carried by said shaft within the die for feeding' the nibs or punchings laterally away from the punches, and to one end of the die.

3. In a record strip perforating machine,

the combination with the frame, a series of punches and die with which `the punches co operate to perforate the recordstrip, of a paper feed shaft extending longitudinally o f the die, pin wheels mounted on said shaft for feeding the record strlp, and a spiral movable in unison with the shaft for feeding the nibs or punchings laterally toward the end of the die, whereby they are removed transversely of the strip.

-L In a record strip punching machine, the combination with the frame, and die, of a paper feed shaft, pin Wheels mounted on `said shaft in position to cooperate with the papel' strip at the ends of the die, one of sald wheels having an aperture therethrough,.

anda conveyor mounted intermediate the pin wheels for transferring the nibs or piinchings toward the end of the die and in position to discharge through the aperture in the pin wheel.

In a record strip punching machine,the combination with the frame, and die, of a paper feed shaft, a pair of pin Wheels mounted on said shaft in position to cooperate with the paper strip at the ends of the die, one of said wheels having an aperture therethrough, a spiral4 conveyer mounted intermediate the pin Wheels for transferring the punches into position to discharge through the said aperture in the pin wheel, a guard mounted on the outer side of the last mentioned pin Wheel to form a chamber for the reception of the punchings, and a conveyer within said chamber for discharging the punchings therefrom.

6. In a perforating machine for record strips, the combination with the frame having an opening therein for the discharge of punchings, \a die, and a rotary paper feed shaft, of a pair of pin wheels mounted on said shaft in position to cooperate with the record strip at the ends of the die, one of said wheels having an aperture therethrough, a spiral conveyer mounted intermed1ate the pin Wheels for transferring the punchmgs into position to discharge through said aperture in the pin wheel, a guard mounted between the outer side of the pin wheel and frame forming a chamber for the reception of said pnnchings, and a conveyer movable with the paper feed shaft for discharging the punchings from said chamber through the aperture in the frame.
